Rovinj's diving spans shallow beginner reefs, complex cave and wall systems, and deep wrecks that demand advanced certification. Most sites are reached by boat, and the topography varies from sloping canyon reefs like Sturag to vertical drops at Reef Rubin and the historic Baron Gautsch wreck. The Seahorse and European Common Cuttlefish are the region's signature finds, while the Tompot Blenny, Scorpionfish, and Cratena Slug appear across virtually every site. Conditions are warmest in autumn, with late summer through October drawing the most diver activity.

Rovinj caters well to beginner divers, with a good number of shallow reef and canyon sites such as Sturag, Sveti Ivan, and Insel Katarina covering a manageable depth range. Advanced divers are well served by deep wrecks like the Hans Schmidt and the Baron Gautsch, as well as wall dives at Kampanil Mali and Reef Rubin. Intermediate options such as Gustinja and Porer Reef fill the gap between the two.
The vast majority of dive sites in Rovinj are boat-access only, so most dives are conducted with one of the local operators. Pal Sv Nikola is a notable exception, offering both boat and shore entry. Several operators are based in the area, including Rovinj-sub Diving Center, Star Fish, and Adriatic Diving Center, which run regular boat trips to the offshore reefs and wrecks.
Rovinj offers considerable variety: reef dives range from shallow rocky formations to steep walls and drop-offs, while cave systems add overhead environment to sites such as Kampanil Mali and Insel Katarina. Wrecks are a notable draw, with the Baron Gautsch and Hans Schmidt both lying deep and suited to experienced divers. Artificial reef structures are present at several sites, extending the habitat available to marine life.
